WORK-HOLDER.

Specification of Letters Patent.

Application filed July 21, 1910.

Patented Jan. 10, 1911. Serial No. 573,139.

To all whom it may concern:

Be it known that I, JAMES A. DE Bonn, a citizen of the United States,residing at Temple, in the county of Bell and State of Texas, haveinvented a new and useful lVork-Holder, of which the following is aspecification.

This invention relates to work holders and its object is to provide asimple device of this character particularly designed for holding doors,window sashes, shutters and the like on edge while being mortised ortrimmed.

One of the objects of the present invention is to provide a simpledevice which can be readily set up at any point and which will firmlyhold the object worked and prevent it not only from swinging laterallybut also from sliding in the direction of its length.

A further object is to provide a work holder which can be adjusted towork of different sizes and also to properly engage an irregularsupporting surface as well as a smooth level surface.

With these and other objects in view the invention consists of certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :Figure 1 is a front elevation of the work holder, thesame being shown in position upon a door standing on end. Fig. 2 is aside elevation of the holder, the same being shown in position upon adoor resting upon one of its longitudinal edges. Fig. 3 is a' plan Viewof the work engaging head of the holder, the supporting legs beingbroken away. Fig. 4 is an enlarged section through one of the clampingmembers carried by the head and showing one means which may be employedfor connecting the clamping member to its adjusting screw.

Referring to the figures by characters of reference 1 designates a yokelike head sufficiently large to straddle the edge of a door,window-sash, blind or the like, this head being provided, in one side,with an adjusting screw 2 the inner end of which may, if desired, beprovided with a ball 3 seated within a socket 4 formed within a disk 5constituting a work clamping jaw. The ball 3 may be retained within thesocket by means of a holding plate 6 having an opening 7 for thereception of the screw 2. It is of course to be understood that othermeans may be employed for mounting the jaw for universal movement uponthe adjusting screw. The working face of the jaw is preferably providedwith a soft covering such as indicated at 8. Another jaw 9 is connectedto the opposite portion of the head 1 and is mounted upon a stud 10extending from said head, the connection between the jaw and stud beingpreferably similar to the connection between the jaw 5 and screw 2.

A bolt 11 is extended transversely through the head 1 and one endthereof is engaged by a tightening nut 12. A spacing sleeve 13 Y ismounted on the middle portion of the bolt and interposed between thissleeve and each side of the head 1 is a pair of eyes 14 and 15 mountedfor rotation upon the bolt 11. Each eye 14 is formed at the upper end ofan angular rod 16 constituting the upper member of a side leg 17 thelower member of .this leg being tubular, as shown at 18 and slidablyengaging the rod 16, there being any suitable means, such as a set screw19, for locking the tubular member 18 in any desired position upon themember 16. A curved bit 20 extends from the lower end of the member 18and is pointed so as to firmly engage the structure on which the workholder is mounted.

The eyes 15 are formed at the upper ends of the upper members 21 of thefront legs 22 of the holder. These members 21 are 1n the form of rodsslidably mounted within the lower tubular members 23 of the front legs,there being any suitable means, such as set screws 24, for locking themembers 21 and 23 together. The lower end of each member 23 has a bit 25extending therefrom, and which is curved, as shown in Fig. 2, each bitterminating in a point adapted to firmly engage the supportingstructure.

In using the device, the jaw 5 is adjusted away from the jaw 9 so as topermit the door or other device to be inserted between the two jaws. Jaw5 is then adjusted toward the jaw 9 by means of a screw 2 so as to causethe two jaws 5 and 9 to tightly clamp upon the work. The legs 17 and 22are then swung upon the bolt 11 until they assume desired positionsrelative to the head and work and each of the legs is then extended orshortened so that the bit carried thereby will properly engage thesupporting the legs relative to the head can be 'aried at will, it willbe seen that the holder can be adapted for use on irregular and inclinedsurfaces as well as upon smooth level surfaces.

Various changes can of course be made in the construction andarrangement of the parts without departing from the spirit orsacrificing any of the advantages of the invention as defined in theappended claims.

hat is claimed is 1. A device of the class described includ ing a workreceiving yoke, work clamping devices carried by the yoke, legspivotally connected to the yoke, each of said legs being extensible, andmeans for securing the legs against pivotal movement relative to theyoke said legs being disposed out of alinement said legs being extendedbeyond the sides of the work within the head.

2. A device of the class described including a work receiving head,means carried thereby for clamping upon the work within the head,longitudinally adjustable legs pivotally connected to the head, meansfor securing the legs against pivotal movement relative to the head andmeans for securing each of the legs against longitudinal adjustment,said legs being extended beyond the sides of the work within the head.

8. A device of the class described including a head for receiving work,work clamping devices carried by the head, extensible legs movablyconnected to the side portions of the head, and support engaging bitscarried by the legs certain of said legs being adapted to straddle theengaged work.

4:. A device of the class described including a head, work clampingdevices carried thereby, legs pivotally connected to the side portionsof the head, each of said legs being adjust-able longitudinally, and acurved bit carried by each leg for engagement with the supportingstructure, all of said legs being out of alinement with the held workand certain of said legs being adapted to straddle the work.

5. A device of the class described including a work receiving yoke, workclamping devices carried thereby, a transversely extending pivot devicewithin the yoke, legs pivotally mounted upon said device and out ofalinement with the engaged work, certain of said legs being adapted tostraddle the work.

6. A device of the class described including a work receiving yoke, workclamping devices carried thereby, a transversely extending pivot devicewithin the yoke, legs pivotally mounted upon said device within theyoke, legs pivotally mounted upon said device and out of alinement withthe engaged work, certain of said legs being adapted to staddle thework, and means engaging the pivot device for clamping the legs and theyoke together to hold them against relative movement.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.

JAMES ALEXANDER DE BORE."
